OME-XML - Open Microscopy Environment XML

OME-XML is a vendor-neutral file format for biological image data, with an emphasis on metadata supporting light microscopy. It can be used as a data file format in its own right, or as a way of encoding metadata within a TIFF or BigTIFF file (for which purpose there is the OME-TIFF specification).

The standard is maintained by the Open Microscopy Environment Consortium, and was last updated in June 2012.
